Android Espresso test error: No static method loadSingleServiceOrNull()

Question

1 周前我运行的测试一切正常，但现在我收到此错误：

java.lang.NoSuchMethodError: No static method loadSingleServiceOrNull(Ljava/lang/Class;)Ljava/lang/Object; in class Landroidx/test/internal/platform/ServiceLoaderWrapper; or its super classes (declaration of 'androidx.test.internal.platform.ServiceLoaderWrapper' appears in /data/app/com.domain.myapp-1/base.apk)

at androidx.test.espresso.DaggerBaseLayerComponent$ViewInteractionComponentImpl.viewInteraction(DaggerBaseLayerComponent.java:1)

这一行抛出错误：

onView(withId(R.id.sign_in_button)).perform(click())

可能是什么原因？谢谢。

Answer 1

你有多个ServiceLoaderWrapper，真正有API方法的是其中的一些，这个文件是androidx.test:monitor带来的，我通过强制版本修复了它应用 gradle 文件中的包如下。

android {
  ...
  configurations.all {
    resolutionStrategy {
        force 'androidx.test:monitor:1.4.0'
     }
  }
  ...
}

我更新时遇到问题

androidTestImplementation 'androidx.test.espresso:espresso-core:3.3.0'

至

androidTestImplementation 'androidx.test.espresso:espresso-core:3.4.0'

恢复到版本 3.3.0 修复了一些问题。
